From time to time I reveive error when getting SCM changes from Git repository and the option "SCM checkout retry count" (I have set it to 3) is not working.

ERROR: Problem fetching from origin / origin - could be unavailable. Continuing anyway
hudson.plugins.git.GitException: Command "git fetch -t git@github.com:xxx/xxx +refs/heads/:refs/remotes/origin/" returned status code 128:
stdout:
